IPhone security is impeccable？ Unofficial cracking has turned the ＂iron wall＂ into ＂paper paste＂!
Cctv newsRecently, the reporter used the keyword "crack iPhone" to search on Taobao. As a result, a large number of services called "professional activation" and "remote unlocking" appeared on the page, claiming that the locked iPhone can be easily cracked.
As a mobile phone known for its security, the iPhone’s "iron wall" seems to be "paper paste" in Taobao sellers, and it will be broken in a few minutes or a few days. How do these sellers do it? As our most important "possessions", is the security performance of mobile phones reliable?
Open these "cracked iPhone" sellers’ pages. There are hundreds of single businesses and dozens of them. It seems that this market is not small. When the comments were opened, there was a lot of applause, and the satisfaction of buyers was beyond words.
Looking through their messages, we will find that they have different purposes to crack their mobile phones: the mobile phones are picked up, cracked and reused; Forgot the power-on password and tried to be locked for many times; IPhone lost, need to remotely erase ID, and so on. Different purposes correspond to different treatment methods, and naturally correspond to different levels of price.
According to industry insiders, there are still some "unspeakable reasons", for example, mobile phones are stolen."Seriously speaking, the cracking service provided by these sellers has become a part of the mobile phone theft industry chain. However, buying and selling have their own needs, and tacitly, it also makes the mobile phone cracking industry a regulated ‘ Grey zone ’ 。”
The reporter tried to get in touch with several Taobao sellers, and the other party’s response was basically the same routine. That is,Tell your story first — — Whether the mobile phone is picked up or your own, whether you forgot your ID or password, and so on. When the reporter explains his purpose, the other party gives instructions concisely — — Hand over the IMEI code of iPhone.
IMEI (International Mobile Equipment Identity) is the abbreviation of International Mobile Equipment Identity Code, which is an electronic serial number consisting of 15 digits. After assembly, each mobile phone will be given a set of globally unique numbers.
Taobao shop owner’s "solution", experts judge, there are several possibilities. "The reason why they say it will take a few days is that they don’t guarantee that they can crack it. It is likely that it will take a few days to ‘ Collision with the library ’ 。”
"Crash into the library" is an attack method. Hackers collect the leaked user name and password information on the Internet, generate corresponding dictionary tables, and use technical means to go to some websites to "try their luck" one by one and try to log in.For example, take the iTunes password that the user has leaked to try the boot password.
In addition, several Taobao stores that the reporter asked all said that they could not save data after "cracking". Some of them are simple and rude, such as directly restoring the factory settings of mobile phones.Experts explained that the user’s choice of "unlocking" in this way is equivalent to "pushing the house when the door key is lost", which is definitely a "high-risk operation". In addition to extreme situations such as picking up or even stealing a mobile phone, contacting the official is the right way.
At the same time, their possible practices include cracking the mobile phone device itself, monitoring or intercepting user information during transmission, etc. "Although there are few loopholes in the operating system of the iPhone, even the most secure system may exist ‘ Zero-day vulnerability ’ 。” Experts are blunt.
"zero-day vulnerability", also called zero-day attack, refers to a security vulnerability that is exploited maliciously immediately after being discovered.The WannaCry ransomware that broke out in 2017 was developed by hackers with the attack code leaked by the National Security Agency. In other words, the loopholes held by the government were obtained and exploited by hackers.
"Security is a relative concept." Experts have repeatedly stressed that, especially at the moment when various applications are emerging one after another, any operation must be networked, and any loopholes may be magnified. "Mobile phones have various security settings and data can be encrypted. However, from the perspective of computational science, the current encryption mechanisms can not ensure absolute security, and cryptanalysts are constantly looking for loopholes in these algorithms. What we can do is to make the hacker’s attack so costly that they have to give up. In other words, there is no safest, only safer. "
